Reactive power support from distributed generation — Ireland´s demonstration initiative

The integration of increasing penetrations of renewable energy sources is one of the key drivers for the increased deployment of control and optimization on power systems. Much of this wind generation is connected to the distribution system, which presents a range of challenges to the operation of these networks, traditionally utilized solely for power delivery. This paper describes a demonstration programme in Ireland which addresses key challenges in delivering high penetrations of wind energy in a cost effective and efficient manner. The paper addresses the advanced reactive power control capabilities of modern wind turbines, along with other voltage control technologies, investigating how these resources can be better utilized from a distribution and transmission perspective.
